It is not uncommon for menstrual blood to come into contact with the toilet bowl or walls during bowel movements, especially if you are experiencing a heavier flow. Menstrual blood can be quite viscous and may cling to surfaces more than other bodily fluids. This phenomenon is generally not a cause for concern and is often just a result of the mechanics of how your body is functioning during that time of the month.

When menstruating, the uterus sheds its lining, which is expelled through the cervix and vagina. If you are also having a bowel movement, the pressure and movement can cause menstrual blood to be expelled in a way that may lead to it splattering or sticking to the toilet walls. This is particularly true if you are using a menstrual product like a tampon or menstrual cup, as the flow may be more pronounced when you are not using these products during a bowel movement.

However, if you notice any unusual changes in your menstrual blood, such as a significant change in color, consistency, or odor, or if you experience any discomfort, pain, or other gastrointestinal symptoms, it may be worth consulting a healthcare professional. These could be signs of underlying conditions that may need to be addressed.

As for gastrointestinal issues, while it is possible for certain conditions to affect your menstrual cycle or the way your body expels menstrual blood, the act of menstrual blood sticking to the toilet walls during a bowel movement is not typically indicative of a gastrointestinal problem. Conditions like endometriosis or fibroids can cause changes in menstrual flow and may lead to discomfort, but they would usually present with additional symptoms.

If you are concerned about your menstrual health or if this is a new occurrence for you, it might be beneficial to keep track of your menstrual cycle, flow, and any accompanying symptoms. This information can be helpful for your healthcare provider if you decide to seek advice.

In summary, while it is generally normal for menstrual blood to stick to toilet walls during bowel movements, if you have any concerns about your menstrual health or experience other symptoms, it is always a good idea to consult with a healthcare professional for personalized advice and reassurance.
